Embodiment Construction
[0009] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0010] As shown in the figure, the present invention includes a body 1 and a heat treatment process. The body 1 is set as a "U"-shaped structure, and a circular through hole is provided in the middle, which is set as the first through hole 2, and the right side There is a through hole on the upper and lower sides of the body, which are respectively the second through hole 3 and the third through hole 4. The front side of the body is provided with a gap 5. The heat treatment process is characterized in that after heating to austenitization Immerse in a suitable quenching medium to cool at a faster rate.
[0011] When selecting the quenching medium for the heat treatment process, sufficient cooling capacity should be ensured first, that is, the quenching medium with high cooling capacity should be selected, and distortion and quenching cracking should also be p...

The invention discloses an injection molding machine pressing plate connecting piece and a heat treating process thereof, including a body and heat treating steps, wherein the body is set as a U-shaped structure, the middle of the body is provided with a circular through hole which is set as a first through hole, the upper side and the lower side of the right side of the body are respectively provided with a second through hole and a third through hole, and the front side of the body is provided with a notch. The heat treating process of the injection molding machine pressing plate connecting piece is characterized in that the injection molding machine pressing plate connecting piece is immersed into an appropriate quenching medium after being heated to austenitizing temperature so as to be cooled at a faster speed. The injection molding machine pressing plate connecting piece has enough tensile strength so as to resist stretching, pull-apart, thread slipping and wear, has higher fatigue resistance and impact toughness properties so as to resist fatigue and impact fracture, and can be well applied to an injection molding machine.
Description
technical field [0001] The invention relates to a mechanical product, in particular to a connecting piece of a pressing plate of an injection molding machine and a heat treatment process thereof. Background technique [0002] Some injection molding machine pressure plate connectors on the existing market cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and impact fracture, and cannot be well used in In the injection molding machine. Contents of the invention [0003] The invention provides a connecting piece of a pressure plate of an injection molding machine and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that some existing injection molding machine pressure plate connecting pieces do not have high enough tensile strength to resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness ar...
